I just added a new email address to my curve which somehow corrupted my calendar data (trying to view/edit an appointment gave the error "Appointment deleted externally. Changes will be lost and the viewer closed.")

I did a battery pull which then removed all of my calendar data which I had thankfully just backed up last night. However, now when I plug my curve into the computer, DM can't find it. Other than adding a new email account nothing else has changed.

I can't figure out what one would have to do with the other, any suggestions? I will try reinstalling DM but I thought I'd ask anyway.
